General description
Protopine is a celandine alkaloid and a bioactive compound associated with the plant families including fumariaceae, berberidaceae and papaveraceae. It is metabolized by demethylenation in the presence of the cytochrome enzymes cytochrome P450 family 2 subfamily d polypeptide 1 (CYP2D1) and cytochrome P450 family 2 subfamily c polypeptide 11 (CYP2C11).
Application
Protopine hydrochloride may be used in the calibration curve preparation for the quantification of alkaloids from Fumaria capreolata using liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry (LC-DAD-MS) and tandem mass spectrometry(MS/MS). It may also be used as an alkaloid in cytotoxicity and permeability studies carcinogenic cell lines.
Biochem/physiol Actions
Protopine possesses anti-parasitic, antimicrobial and anti-inflammatory property. It mediates mitotic arrest by favoring tubulin polymerization. Protopine elicits anti-invasive effects in breast cancer tumor progression.. It also provides protection against oxidative stress-induced cell death.
Protopine hydrochloride is a Ca2+ channel blocker and antiplatelet agent.
Caution
Protect from light.

For the synthesis of protopine alkaloids, we studied a reaction sequence based on a ring enlargement of indeno[2,1-a][3]benzazepines by a singlet oxygen oxygenation, followed by conversion of an amide carbonyl group of the resultant 10-membered keto-lactam to a methylene group

S-Adenosyl-l-methionine:tetrahydroprotoberberine cis-N-methyltransferase (EC 2.1.1.122) catalyzes the conversion of (S)-stylopine to the quaternary ammonium alkaloid, (S)-cis-N-methylstylopine, as a key step in the biosynthesis of protopine and benzophenanthridine alkaloids in plants. A full-length cDNA encoding a protein exhibiting 45 and 48% amino

pH-zone-refining counter-current chromatography was successfully applied to the separation of alkaloids from a crude extract of Corydalis decumbens (Thunb.) Pers. using a multilayer coil planet centrifuge (CPC). The experiment was performed with a two-phase solvent system composed of methyl tert-butyl

The protopine isolated from a Chinese herb Dactylicapnos scandens Hutch was identified as an inhibitor of both serotonin transporter and noradrenaline transporter in vitro assays. 5-hydroxy-DL-tryptophan(5-HTP)-induced head twitch response (HTR) and tail suspension test were adopted to study whether protopine
Journal of pharmaceutical and biomedical analysis, 59, 44-49 (2011-10-26)
With the application of near-infrared spectroscopy (NIRS), a convenient and rapid method for determination of alkaloids in Corydalis Tuber extract and classification for samples from different locations have been developed. Five different samples were collected according to their geographical origin
